Since 2009, he and his company, Lightstorm Entertainment, have also received a flurry of lawsuits from others claiming "Avatar" was their idea.

Just in case anyone else wants to stake a claim in what Cameron has described as his "most personal film" to date, he wants everyone to know that he had the idea for his film long before both "FernGully" and Disney's "Pocahontas."

In fact, Cameron claims he's had initial concepts for "Avatar" floating around since the '60s.

In a lengthy 45-page sworn declaration filed at the end of October, Cameron once and for all laid out the details of how he came up with the idea for Hollywood's blockbuster.

Rip-offs? No.

In the document which you can read HERE, Cameron details how basically every single element in his film was inspired from previous artwork, themes, and characters from never produced projects and films made before 1991.

Essentially, Cameron claims "Avatar" is the byproduct and combination of four early sci-fi projects: "Xenogenesis," "Chrysalis," "Mother," and "Wind Warriors."

Here are the plot synopses for the four films Cameron claims "Avatar" borrows:

"Xenogenesis":

"Xenogenesis is the saga of the voyage of Cosmos Kindred, a mile-long spaceship employing a fusion ramjet interstellar drive unit. In the face of destruction of the Earth, scientists engage in a last-ditch effort to preserve a nucleus of humanity by trying to find a new planet on which to live … "Xenogenesis" explored the concept of actual “linking” between human and machine, or mind-machine interfacing."

"Chrysalis":

"The script describes a cosmic journey of self-discovery and transcendence taken by a wheelchair-bound man who elects to surgically remove all external sensory input, so that he can journey through his own mind."

"Mother":

"Humans have plundered Earth and look to exploit another planet. As I wrote in 1980-81: “It was a … plan, born of desperation. For Earth was becoming hell too, crushed beneath a sea of homo sapiens, and they needed new territory. Not simply a new continent: an entire world was required. And so they came.” This effort is spearheaded by an international and interplanetary consortium called Triworld Development Corporation, or “the Company,” which sets up mines on another planet, possibly Venus or an extrasolar planet or moon such as Titan."

"Wind Warriors":

"An aviatrix crashes into the Brazilian rainforest and mysteriously disappears. Her daughter travels to the jungle in order to search for her mother and, together with an archaeologist who speaks the language of the natives, hire a bush pilot to take them upriver in his converted World War I bomber plane. They are attacked by mercenaries under the command of a greedy industrialist, who is seeking a mysterious but extremely valuable metal. The industrialist has an airship, which the indigenous warriors believe to be a god, and he uses the airship to make them dig for more of the metal."

Here are some of the detailed examples Cameron says are borrowed from the films:

"Xenogenesis":

His idea for Pandora (the world featured in "Avatar") was modeled after another location featured in the late '70s science-fiction script.

"I modeled Avatar’s Pandora on one of the planets that the characters explore in Xenogenesis. This planet in Xenogenesis, the Luminous Planet, has a beautiful forest with a vast network of interconnected, bioluminescent trees. The human characters cannot survive on this planet because of its deadly atmosphere."

Note that the original idea for Pandora stemmed from a drawing of an alien jungle landscape drawn in 11th grade.

"For example, in the eleventh grade, I did a pen drawing entitled 'Spring on Planet Flora' ... This drawing depicts an oversized jungle environment of an alien world that I conceived, which I called “Planet Flora.”

"The landscape depicted in “Spring on Planet Flora” is essentially the same in concept and detail to the alien jungle landscape on the moon Pandora, on which much of the action in Avatar takes place."
